The Electric Bicycle

The Electric Bicycle

From the beginning of my journey in 2018 until February 2024, I have been riding with a 2018 Riese und Muller Supercharger GT Nuvinci/Enviolo HS. It had a dual battery system with two 500 Wh Bosch Powertube batteries. After 82,000 kilometers, the batteries didn’t work well enough for me to continue the journey. I decided to purchase another ebike.
I changed the Bosch drive unit motor once after 30,000 kilometers. The second drive unit motor was working fine after 52,000 kilometers.
I changed the carbon belt after 60,000 kilometers.
I changed the Enviolo hub after 60,000 kilometers although it was still working.
I changed the tires (Schwalbe Super Moto X) every 20,000 kilometers. I only had 4 flat tires in the entire journey.

The new ebike is a 2023 Riese und Muller GT Rohloff HS with dual batteries (two 625Wh batteries).

Although my electric bicycle allows for speed up to 45 kilometers per hour (28 miles per hour), my average speed is around 27 kilometers per hour (17 miles per hour). For security reasons, to save the batteries electricity and to enjoy my surroundings, I find it more enjoyable to ride at a reasonable speed.

How efficient is my electric bicycle?

The average cost of electricity in the world is 0.138 U.S. dollar per kWh. On average, my electric bicycle can ride about 100 kilometers per kWh. So the cost of electricity has been around 0.138 dollar for every 100 kilometers of cycling. 
Having cycled 50,000 kilometers in close to two years so far, the total cost of electricity used has been about 69 dollars.

The same journey of 50,000 kilometers in a midsized car would have cost about 3,700 dollars in gasoline. (The average price of gasoline around the word is 1.23 U.S. dollar per litre).

The same distance travelled on an airplane by a person would require about 1,500 litres of jet fuel at a cost of 0.8 dollar per litre. A total cost of 1,200 dollars.
